这次吊装是前所未见的
8月10日 被高高吊起，向着核岛方向移动。 吊装成功！ 压力容器、蒸发器等关键设备一步到位， 玲龙一号全球首堆的安装工作步入高峰期。 这是玲龙一号核岛设备安装关键路径上的第一个里程碑节点，是核反应堆模块化制造和安装的一次“首秀”，代表全球核能小型化迈出了历史性一步，标志着我国在模块式小型堆建造上走在了世界前列，也是中核集团把主题教育与重大工程建设结合起来，扎实推进主题教育在以学铸魂、以学增智、以学正风、以学促干方面走深走实、见行见效的生动实践。 为确保工程质量全面可控，项目团队统筹谋划设备验收、出厂、转运、接收、吊装工作，在监管当局全程严格监督下，海监、设备厂商、现场建设团队通力配合，有效克服了天气复杂多变、设备稳定性要求高、首堆经验缺乏等多种困难，终于达成了“充分准备，一次成功”的目标。 World's first! "The Heart of Linglong One" in place On August 10th, the core module of the Linglong One reactor, a multi-purpose modular small reactor in Hainan, a subsidiary of China National Nuclear Corporation (CNNC), was lifted and moved towards the nuclear island. Pressure vessel, evaporator and other key equipment were installed in one step, marking the peak phase of Linglong One’s installation. This is the first milestone of the installation of Linglong One nuclear island. It marks the debut of modular manufacturing and installation of nuclear reactor modules, representing a historic step of global nuclear miniaturization and highlighting China's leading position in the modular manufacturing of small pressurized reactor units. The core module, also known as "the heart of Linglong One", is Linglong One’s core components. It integrates pressure vessel, evaporator, and primary pump receiver, and removes the main pipeline. The steam generator is inside the reactor pressure vessel. Before the lifting, the steam generator already undergone joint welding with the reactor pressure vessel at the factory, effectively integrating the "lungs" and "heart" of the nuclear power plant. It is the most challenging and representative nuclear power main equipment featuring "factory prefabrication and modular manufacturing" processes. The design and construction of Linglong One are revolutionary and groundbreaking. Modular construction is its most prominent feature. Through standardized design, single module production, and mass production, it shortens the construction period and reduces costs while improving safety. The modular small reactor has a simplified system and small size, which is convenient for transportation and operation. It allows flexible adjustments and construction according to users' requirements, resulting in significant economic benefits. The Hainan Nuclear Power Multi-purpose Modular Small Reactor Technology Demonstration Project is the world's first commercial land-based small modular pressurized water reactor. Upon its operation, it is expected to generate one billion kilowatt-hours of electricity per year, which could meet the needs of 526,000 households and is equivalent to reducing around 880,000 tons of CO2 emissions or planting 7.5 million trees. With its stable and reliable clean energy supply, it will contribute to China’s carbon peaking and carbon neutrality goals and the construction of a "clean energy island" in Hainan, and drive the development of nuclear energy worldwide.
